The role of high-frequency welding, preheating before welding, and post welding heat treatment
2025-02-17
High frequency welding is a commonly used welding method for connecting metal materials. Preheating before high-frequency welding is an essential step. The main function of preheating before welding is to raise the temperature of the material to a sufficient welding temperature, thereby ensuring the quality and reliability of the welding. Preheating helps to eliminate internal stress in materials, improve metal ductility and plasticity, and reduce the occurrence of welding defects. In addition, preheating before welding can improve the affinity of the welding interface, promote the flow of welding agent, and enhance the firmness and sealing of the welded joint.
